What do you assign to Mordor? And why?
Work. Because it's inhumane.
Cat litter. If Tolkien was going to put Siamese cats in there (and I hope he only meant Siamese cats and not all cats), then the litter can go with them. It can't smell any worse than orcs.
Celery. What's the point of it? As someone said to me today, it's just a means of conveying dip to your mouth.
Faceless bureaucracies belong in Valinor though.
